Leaving the root ends intact, cut escarole (or romaine) heads into quarters (the root will keep the leaves from falling apart); brush the cut sides with the garlic-oil mixture and sprinkle with 1/4 teaspoon salt. Season both sides of steak with the remaining 1/4 teaspoon salt and 1/4 teaspoon pepper. Pat the remaining 1 tablespoon Parmesan onto both sides of the steak.

Oil the grill rack (see Tip). Grill the escarole (or romaine), turning occasionally, until the inner leaves have softened and the outer leaves have begun to char, about 4 minutes total. Transfer to a cutting board to cool. Grill the steaks, turning once, until desired doneness, 8 to 12 minutes total for medium.

Cut the root ends off the escarole (or romaine) and discard. Chop the leaves into bite-size pieces. Serve the steak and grilled greens drizzled with the reserved tomato vinaigrette.

Tips:

Tip: To oil the grill rack: oil a folded paper towel, hold it with tongs and rub it over the rack. Do not use cooking spray on a hot grill.
